Halfway Between 5 and 20

When you ask "What number is halfway between 5 and 20?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=5 and Y=20.

Halfway Between Line

To find the number halfway between 5 and 20, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 20 into our formula, we get:

(5 + 20)/2 = 12.5

Thus, the number halfway between 5 and 20 is 12.5.

To check that our answer is correct, we subtract 5 from 12.5 and subtract 12.5 from 20 and compare the two numbers:

12.5 - 5 = 7.5
20 - 12.5 = 7.5

As you can see, the halfway number is 7.5 higher than 5 and 7.5 lower than 20. Therefore, our halfway between answer of 12.5 above is correct.
